Hi Gordon, thanks for the feedback and sharing all your findings with us here! Thank you very much for writing this article!!! Ask Question Asked 3 years, 11 months ago. For these YCSB workloads, MongoDB/HSE workloads.

Concurrency is a difficult thing to test since it is non-deterministic, so how do we test if this even works? HSE is an embeddable placement across DRAM and multiple classes of SSDs or other
You then wait for the specified time then asynchronously run the block which updates the photos count and updates the prompt. public typealias Iterator = IndexingIterator swiftQueue, founded in 2011 by Brendan Casey and Declan Donohoe, are transforming the way healthcare clinics operate within hospitals across the HSE in Ireland and the NHS in the UK.

I would add that I eventually had to change all “queue.async..” lines to “queue.sync..” to prevent some sequencing problems. Air dates March 31-April 6, 2019 & September 29-October 5, 2019 Chimney Swifts, Paddlefish Progress & Tree Stand Safety Swift Saviors From … return result

#eh2030 Health Innovation Showcase. That would be helpful.

Touch Screen Tablet & Kiosk Check In Reduce … Thanks! That might work for concurrent reads, but we must disallow all concurrency when writing. Here’s a little script that shows thread-safety issues when modifying arrays concurrently.

guard iterations <= 0 else { return } Swiftqueue was founded in 2011 and from day one has received excellent feedback by providing solutions that are easy to use for both patients and clinics coupled with excellent customer support. } }, Very cool, thx!

var result = SynchronizedArray() DispatchQueue.concurrentPerform(iterations: iterations) { index in, kernel(index) We use optional third-party analytics cookies to understand how you use GitHub.com so we can build better products. } you just made my day .

We also integrated HSE with MongoDB®, let message = String(format: "Unsafe loop took %.3f seconds, count: %d.

If I am thinking right, all read operators would run serially? return iterator!

Fill in work details - this is to help with reporting. See how I implemented multiple queues there: http://basememara.com/swifty-locations-observables/.

found in the YCSB section Would this help your scenario? For more information, see our Privacy Statement. So you dispatch another task asynchronously to the main queue to trigger the notification. iterations -= 1, // Final loop Let’s encapsulate everything we learned into a nifty, thread-safe array called `SynchronizedArray`. of the HSE Wiki.

It should execute the closure after it does its action on the array. Que signifient ces lettres et ces chiffres ? Instead, we have to go through Grand Central Dispatch.

If nothing happens, download the GitHub extension for Visual Studio and try again. This means no other blocks may be scheduled from the queue while the async/barrier process runs.

Just wondering how it might be possible to use SynchronizedArray with multiple concurrent queues. I copied/pasted the code into a swift source files and use the swift package manager environment on a MacOS (all updated no worries on versioning).

We continue to use the sync method for reads, but all readers will run in parallel this time because of the concurrent queue attribute. Thread-safety is a tricky territory, especially in languages like Swift where there is no built-in concurrency support. Swiftqueue never shares information with third parties.

Please help me the solution. Swiftqueue were delighted to be a part of the e-Health Ireland Health Innovation Showcase in Trinity Science Gallery on 22nd and 23rd November 2016.

func Test2() { With a serial queue, only one process can run at a time, so if many processes are stuffed in a queue to modify the array, the serial queue will only let one process execute at a time; the array is safe from concurrent processes by design. We keep in constant contact with our Customers to ensure we continually develop our solution to meet their growing requirements and to simplify any repetitive tasks and continuous innovation.
